Question

How do producers make their own food?

Answer 1

Producers synthesize their own food by the process of photosynthesis.

Explanation:

Producers are termed autotrophs . These plants have a green pigment called chlorophyll, which traps sunlight needed for the process of photosynthesis.

Photosynthesis occurs in 2 steps:

1. Light reaction or Hill's reaction
2. Dark reaction or Blackmann's reaction

Light reaction occurs in light. During this step, photolysis of water occurs in presence of light. `O_2` is liberated and solar energy is converted into `"ATP"` and the reducing power `"NADPH"` is produced.

During the dark reaction, `CO_2` is reduced to glucose ( `C_6H_12O_6`) in a series of steps with the help of `"ATP"` and `"NADPH"` produced during light reaction.

Glucose is converted later into starch and other organic compounds during various metabolic reactions.
